/**
Makes a SAL procedure call.
This is a wrapper function to make a SAL procedure call.
No parameter checking is performed on the 8 input parameters,
but there are some common rules that the caller should follow
when making a SAL call. Any address passed to SAL as buffers
for return parameters must be 8-byte aligned. Unaligned
addresses may cause undefined results. For those parameters
defined as reserved or some fields defined as reserved must be
zero filled or the invalid argument return value may be returned
or undefined result may occur during the execution of the procedure.
This function is only available on IPF.
@param Index The SAL procedure Index number
@param Arg2 The 2nd parameter for SAL procedure calls
@param Arg3 The 3rd parameter for SAL procedure calls
@param Arg4 The 4th parameter for SAL procedure calls
@param Arg5 The 5th parameter for SAL procedure calls
@param Arg6 The 6th parameter for SAL procedure calls
@param Arg7 The 7th parameter for SAL procedure calls
@param Arg8 The 8th parameter for SAL procedure calls
@return SAL returned registers.
